DETAILED DESCRIPTION

The present invention provides an earpiece case with shielding. FIG. 1 illustrates one embodiment of the earpiece case housing 10 which includes a charger 12 and a slide cover 14. The charger 12 includes receptacles 11 for placing left and right earpieces. When the left and right earpieces (not shown) are placed within the charger 12, connections are made between contact points on the earpieces and connectors 13. The connectors 13 may be magnetic connectors to make it easier for a user to properly connect the earpieces to the earpiece case housing. Thus, when the earpieces are placed in the charger 12 the earpieces may be charged by the charger 12 such as by using a battery also disposed within the charger 12, or through connecting the charger 12 to a power source such as a USB power source 22, or other type of power source. In addition, data may be communicated through the connectors 13 as well for various purposes including to upload data to or download data from the earpieces. FIG. 2 further illustrates the charger 12 configured to receive earpieces 15 into its receptacles.

FIGS. 3A-3E illustrates the slide cover 14 used to encase a smart case 12 (not shown). The slide cover 14 includes shielding which can serve several different functions. First, the magnetic shielding may be used to shield objects outside of the earpiece case from any effects of the magnetic connectors 13. Second, the shielding may be used to shield the wireless earpieces which may include one or more radio transceivers in at least one of the earpieces from connecting with other devices while the earpieces are within the earpiece case and not in use. Thus, for example, while the earpieces are within the earpiece case, a mobile phone or computer which is sometimes paired via Bluetooth the one or both of the earpieces would not be able to find the earpieces or try to connect with the earpieces or vice versa. FIG. 3A shows three- dimensional view of the slide cover 14. The smart case 12 may be placed into the slide cover 14 through an open side (not shown in this particular figure). FIG. 3B shows a side view of the slide cover 14. FIG. 3C shows an overhead view of the slide cover 14. FIG. 3D shows the open side of the slide cover 14. Two apertures for the status light and the power source connector are shown. FIG. 3E shows the back of the slide cover 14.

The slide cover 14 may be constructed in various ways in order to provide shielding. For example, the slide cover 14 may be formed from a high permeability such as an alloy having high nickel content (e.g. 50 percent or more). Examples of alloys which may be used include Permalloy and Mu-Metal. Of course, any number of other materials may be used provided they allow for adequate shielding. The slide cover 14 may also include mesh material to provide RF shielding and/or a liner.

FIG. 4 shows a cross-sectional view of the ear piece case 10, including the charger 12 and the slide cover 14. The charger 12 may be placed, positioned, or disposed within the slide cover 14 and may be removed from or placed into the slide cover 14 as needed by a user. The charger 12 may be configured to hold one or more earpieces, and may have one or more electrical components installed that may be used to power, operate, or otherwise control an earpiece. The slide cover 12 may be manufactured using scratch-resistant materials, or any materials that would reduce the likelihood of becoming damaged, and may be configured to withstand the force of impact from falls without becoming damaged to the point of inoperability. In addition, the charger 12 may have magnetic and radiofrequency (RF) shielding in addition to any shielding the slide cover 14 provides in order to improve the operability of an earpiece. For example, one or more ends of the charger 12 may have shielding. The charger 12 may also be readily transportable by the user. The slide cover 14 may be configured to encase the charger 12. The slide cover 14 may be composed of scratch-resistant materials, magnetic shielding materials, and/or RF shielding materials depending on the requirements of a prospective user.

The slide cover 14 may have a liner 16 attached to the inside of the slide cover 14 and/or a metal mesh 18 attached to the inside of the slide cover 14, with the liner 16 layered over the metal mesh 18. The liner 16, may include shielding materials, such as magnetic shielding materials or RF shielding materials. Where used, a metal mesh 18 may be attached to the slide cover 14 wherein the apertures are sized, shaped, positioned, or otherwise configured to block EM radiation such as radio waves, especially radio signals at frequencies associated with Bluetooth, or matching the frequencies of the wireless transceiver(s) of the earpiece(s).

The charger 12 may also have one or more additional components installed within, including, but not limited to, a processor, a battery, a data storage device, one or more sensors, a display, or one or more transceivers. The processor may be used to monitor or control one or more earpieces present within the earpiece case housing. The battery may be used to power the processor and other components present within the earpiece case housing or power one or more earpieces present within one or more receptacles of the earpiece case housing. The data storage device may be used to store programs used to modify, monitor, operate, or otherwise control one or more earpieces present in the earpiece case housing. One or more transceivers may be used to communicate with the earpiece case housing when the case is not shielded. One or more sensors may be used to determine when the slide cover 14 removed and potentially terminate the powering of any earpieces present within the earpiece case housing or even to turn one or more of the earpieces on. The charger may also include one or more status lights and/or one or more power or data connectors. The status light may show the status of the power within the earpiece case housing. For example, the status light may illuminate green when the charger is fully charged, yellow when the charger is less than fully charged, and red when the smart case is in need of power. The status light need not have more than one color, however; a single color light that conveys information through changes in luminescence intensity or intermittent flashing may also be used. For example, a solid light may represent a fully charged battery, a light of lower luminescence may represent a less than fully charged battery, wherein the luminescence gradually falls in proportion to the battery level, and a flashing light may represent that the battery needs to be recharged, wherein the flashing may become faster and more pronounced the closer the battery is to running out of power. The power source connector may be configured to connect any type of electrical wiring that is suitable for the earpiece case housing.

According to another embodiment instead of a slide cover, the smart case may be of a clamshell design. One or more hinges may be present to hinge a top portion of the smart case to a bottom of the smart case. The case housing includes at least one receptacle configured to hold an earpiece and at least one connector for each earpiece. The shielding materials may be integrated into smart case to provide for shielding. The case housing may include a first portion and a second portion wherein the first portion and the second portion are moveable with respect to each other to define an open position and a closed position. One of the first portion and the second portion may be a slide cover. The other of the first portion and the second portion may be a charger. Alternatively, the first portion and the second portion may be, for example, a top portion of a clamshell case and a bottom portion of a clamshell case. Of course, any number of other types of configurations are contemplated.

Therefore, a smart case for earpieces has been shown and described which includes magnetic shielding. Although various embodiments have been described, the present invention contemplates numerous options, additions, and variations.
